On April 29, according to the National Mineral Yearbook released by the Ministry of Natural Resources, the number of newly discovered mineral deposits such as salt fields across the country increased significantly in 2025. Specifically, China newly discovered 13 oilfields each with reserves of 100 million tons, and 26 gas fields each with reserves of 100 billion cubic meters. On April 30, an official from the Ministry of Natural Resources stated that in the new round of strategic prospecting breakthroughs, a number of large and medium-sized oil and gas fields have been discovered, and the newly proven reserves have maintained high growth.
Since the launch of the new round of strategic prospecting breakthroughs, China has prioritized oil and gas as the top focus, investing nearly 450 billion yuan in total. A total of 225 large and medium-sized oil and gas fields have been newly discovered in the Tarim, Ordos, and Bohai Bay basins, including 13 oilfields each with reserves of 100 million tons and 26 gas fields each with reserves of 100 billion cubic meters.
The Ministry of Natural Resources stated that China has also achieved “three-dimensional expansion” in oil and gas exploration, with deep and deep‑sea areas becoming new growth poles.
In the deep domain, China’s first 10,000‑meter scientific exploration well — the Deep Earth Tarim No. 1 — successfully penetrated 10,000 meters of strata, and for the first time in the world discovered oil below 10,000 meters.
In the deep‑sea domain, the “Deep Sea No. 1″ ultra‑deepwater gas field was successfully put into operation, propelling China’s deep‑water oil and gas exploration and development capabilities to the forefront of the world, with total offshore oil and gas output exceeding 90 million tons.
The extraction of oil and natural gas cannot be achieved without separation equipment.
Shanghai Shangjiang Petroleum Engineering Equipment Co., Ltd. established in Shanghai in 2016, is a modern technology enterprise integrating R&D, design, production, and service. We are dedicated to developing separation and filtration equipment for the oil, gas, and petrochemical industries. Our high-efficiency product portfolio includes de-oiling/dewatering hydrocyclones, desanders for micron-sized particles, and compact flotation units. We provide complete skid-mounted solutions and also offer third-party equipment retrofitting and after-sales services. Holding multiple proprietary patents and operating under a DNV-GL certified ISO-9001, ISO-14001, and ISO-45001 management system, we deliver optimized process solutions, precise product design, strict adherence to engineering specifications, and ongoing operational support.
Our high-efficiency cyclone desanders, renowned for their exceptional 98% separation rate, have earned recognition from international energy leaders. Constructed with advanced wear-resistant ceramics, these units achieve 98% removal of particles as fine as 0.5 microns in gas streams. This capability enables the reinjection of produced gas for miscible flooding in low-permeability reservoirs, a key solution for enhancing oil recovery in challenging formations. Alternatively, they can treat produced water, removing 98% of particles larger than 2 microns for direct reinjection, thereby boosting water-flood efficiency while minimizing environmental impact.
Our new product——The High Efficiency Ultra-Fine Particle Desander is a liquid-solid separation device that utilizes an efficient centrifugal principle to separate suspended impurities—such as solids in produced water, seawater, condensate, fine particles in high-viscosity liquids, and catalyst powder in reactors—from fluids (liquids, gases, or gas-liquid mixtures). It effectively removes solid particles with sizes down to 2 microns (at 98% efficiency) or smaller.
The High Efficiency Ultra-Fine Particle Desander delivers high sand removal efficiency, capable of removing solid particles down to 2 microns. The equipment features a compact footprint, requires no external power or chemical additives, and has a service life of approximately 20 years. It offers online sand discharge capability without the need for production shutdown.
Proven in major global fields operated by CNOOC, CNPC, Petronas, and others across Southeast Asia, SJPEE desanders are deployed on wellhead and production platforms. They provide reliable solids removal from gas, well fluids, and condensate, and are critical for seawater purification, production stream protection, and water injection/flooding programs.
Beyond desanders, SJPEE offers a portfolio of acclaimed separation technologies. Our product line includes membrane systems for natural gas CO₂ removal, deoiling hydrocyclones, high-performance compact flotation units (CFUs), shale gas desanding，Cyclonic dewater package with produced water treatment，and multi-chamber hydrocyclones, delivering comprehensive solutions for the industry’s toughest challenges.
